PROBLEM TO BE SOLVED: To reduce a control frame transmission time to a node to which intermittent reception is adopted, while maintaining synchronous communication.SOLUTION: A communication device includes: communication control means for controlling a data frame request destination to transmit a control frame over a control frame transmission time, and to transmit a data frame after the transmission of the control frame is completed; transmission means for transmitting either a control frame or a data frame; reception means for receiving a frame; control frame transmission information preservation means for preserving a control frame transmission period and a data frame transmission result, at least at each transmission of the data frame; and control frame transmission control means for determining a control frame transmission time of the next time, on the basis of the control frame transmission period and the data frame transmission result in the past.SELECTED DRAWING: Figure 1 |
